  • Cold galvanizing is also called electric galvanizing. It is the use of electrolytic equipment to remove oil, pickling, and then put the pipe into the solution of zinc salt, and connect the anode of the electrolytic equipment, place zinc plate on the opposite side of the pipe, and connect the positive pole of the electrolytic equipment to the power supply. A layer of zinc is deposited on the pipe fitting by directional movement of an electric current from the positive pole to the negative pole. Cold plated pipe fitting is processed before galvanizing.

  • In strict accordance with the multi-pass small compression rate drawing, the total compression rate is 96.48%, reducing the scraping of zinc layer. The whole wire drawing die is made of tungsten steel die and polycrystalline die. The Angle of the working cone of the wire drawing die is 12° ~ 16°, and the length of the sizing belt is 0.15 of the diameter of the wire, so as to ensure that the deformation of the zinc layer is basically synchronous with the steel wire substrate.

  • Because of the high carbon content, simple cracks occur during water quenching, so double liquid quenching (water quenching + oil cooling) is mostly used, and oil quenching is mostly used for small cross section parts. This type of steel is generally used after quenching by medium temperature tempering or normalizing or in the surface quenching state. Mainly used for manufacturing spring and wear-resistant parts.
